Light waves, visible and invisible

Each kind of light has a unique wavelength, but human eyes can only perceive a tiny slice of the full spectrum -- the very narrow range from red to violet. Microwaves, radio waves, x-rays and more are hiding, invisible, just beyond our perception. Here is a closer look at the waves we can't see.

The whole time I was watching this, I could only focus on how abusive these people are being towards this girl. 0:13 Glad she isn't a guy 0:57 she was definitely set up 1:06 they made her believe that there was actual fishing wire on that rod. 1:21 thats just mean. 1:41 SOUP CANS HURT! and is that wine? 2:24 they definitely spiked her drink... 3:47 VR gone wrong 4:00 they stranded her in the desert and tried to drop things on her head. 4:44 RU-vid Rewind TIME 2019! 5:30 her reminiscing the time before she got captured by TED-Ed...she was told that she is going to be beheaded the following day. Can we get some F's in the chat? R.I.P wooden lady...

Light can be powered by thermo-nuclear fusion like we see in stars, however their are other ways to power light like nuclear fission, chemical molecular reaction, mass colliding with other forms of mass, etc., etc. Light particles/waves can move so fast because they have almost no mass, making it relatively easy for those waves/particles to move at the speed of light.

the energy comes from various places. sometimes it's an electron jumping between orbits with the difference in energy being released as light. So if one orbit requires 3x energy to be in and then the electron drops to an orbit that requires only 1x energy, light with energy 2x is released. And it moves so fast because it is massless and everything that is massless moves at the same rate (popularly called the speed of light)
@Meximagician
@Meximagician 10 лет назад
They simply use a color code to shift the light back into the visible spectrum. You've probably seen this in weather maps on the news, that's just radio waves which are then given a color code. The same thing can be used for infrared (IR) or Thermographic cameras to see heat.

Very good & witty explanation. I want to add one thought: Walkowicz calls radiation "kinds of light"; I'd like a quick clarification - "we say x-rays, microwaves, light, etc. but they are waves, so we'll call it 'kinds of light' for this talk".

@natepepin09
@natepepin09 10 лет назад
I know that there are a few other replies to this, but I think this one is better. Imagine your favorite song, and imagine you play it at 1/100 the speed. The pitch is lowered and it isn't likely to be recognizable. But if someone in the room records it in full, and then speeds it up by 100 times, they will essentially have the original track. In the same way, if the frequency of light is too high for the eye to see, they will stretch it out until it is in the visible spectrum.

light waves are usually shown as being vertical like this ~~~ or vvvvv I suppose that in reality light waves are more complicated than this. They must overlap and coincide and meld and mix and interfere.
@SuperNumber420
@SuperNumber420 10 лет назад
that is true. also, when we see colors, we are very rarely seeing one color. other than pure red, green and blue (i believe those are the three...), whenever we see a color, it is multiple wave lengths of different colors. they are put together and viewed as one color by our brain. pink, yellow, orange, magenta, they are all just different ratios of the red green and blue wavelengths that our visual system translates into one smooth color. it gets much more complex than what this video (or i) describes.

I think the idea of the video was how blind we are and how much we cannot see. If we evolved differently we could maybe see magnetic waves, gamma waves or radio waves. They say the amount of the Electromagnetic spectrum that we can see, if you extended it from New York to Los Angeles is only the size of one single golf ball. That is completely mind blowing.

the waves of light and colors are like waves of the ocean. it could be big or it could be small. this size of wave is called wavelength
@Markus9705
@Markus9705 10 лет назад
"do they convert the wave lengths that are usually out of our spectrum in order for us to see them?" Yeah, you can say that. In order to see the picture we must use visible light, yes.All you need to do is to multiply or divide the values, so you get wave lengths you can see. The cool thing here is that there're more colors than we can experience and see. There are more colors than we know. That's quite mind blowing, actually.
@MrMegaMetroid
@MrMegaMetroid Год назад
Not more colours, just different wavelengths. Remember, lights doesn't have colours, as they are an addition of our brain. Everything outside of our soectrum just wasnt assigned a colour, because we cant detect in anyway. There is however nothing to indicate that the brain would make up a new colour for different wavelengths. All colours are made up by the brain and fitted onto the wavelengths you detect. We dont even know how the brain is doing it, or why its using colour specifically (since it could use basically any sensation to represent wavelengths). Extra fun fact, you CAN use different sensations to represent wavelengths by rerouting where the input is processed in the brain. Light only gets visible because its processed in the visual center of the brain. It can however, be processed in the auditory center and hearing it works just as well. Vice versa that works too. Thats how people on certain psychadelics can taste colours for example. Its all happening in the brain, colour is not a physical phenomenon, and not a property of light itself any more than pain is a property of a hot metal rod.
@nathanaelink
@nathanaelink 10 лет назад
I don't understand.. do they convert the wave lengths that are usually out of our spectrum in order for us to see them? Even if we make a camera that is activated by a certain wave type, how do we get in crammed back into a spectrum OUR eyes are activated by?

I do not know it but i guess you have to edit the pictures (on a computer) by multiply the wave length. Lets say you can see from 1 to 5 and you want to see something between 0 and 1, then you simply multiply every value below 1 with 5 and got a value you are able to see
